A206.0-T4 Cast Aluminum
A206.0-T4 aluminum is A206.0 aluminum in the T4 temper. To achieve this temper, the metal is solution heat-treated and naturally aged. It has the lowest strength and highest ductility compared to the other variants of A206.0 aluminum.
The graph bars on the material properties cards below compare A206.0-T4 aluminum to: ANSI/AA cast aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
